Q. Use the following function rule to find f(−9q)f(-9q). Simplify your answer.\newlinef(j)=8jf(j) = 8j\newlinef(−9q)=f(-9q) = __\_\_
  1. Identify Function Rule: Identify the function rule and the input value.\newlineThe function rule given is f(j)=8jf(j) = 8j, and we need to find the value of f(−9q)f(-9q).
  2. Substitute Input Value: Substitute −9q-9q for jj in the function rule.\newlineUsing the function rule f(j)=8jf(j) = 8j, we substitute jj with −9q-9q to find f(−9q)f(-9q).\newlinef(−9q)=8(−9q)f(-9q) = 8(-9q)
  3. Simplify Expression: Simplify the expression.\newlineNow we multiply 88 by −9q-9q to simplify the expression.\newlinef(−9q)=8×−9qf(-9q) = 8 \times -9q\newlinef(−9q)=−72qf(-9q) = -72q
